Hi,

I find it difficult to explain wat i want to do but I still try.
I also have an example of what I have made now, but it does not do what I want that is to do.

I want to create a Flow that looks at a table.

For every line where column B is 2019 (this year) AND column C is period 4 (previous period) AND has a 1 in a ruleset, an email is sent where i in the body a choice can be made.

I hope sombody can help me☺

Like As:
1001 = 2019 + 4 (column A + B + C)
Has a 1 with ruleset1 and has a 1 with ruleset 3
Then in the mail (Body) column A + B + C and column L + M + R AND column W

This is the table:

This is the flow for so far but it is very bad i think.

You almost got it!

In your "Condition 2" action block, you currently have one evaluation rule (Year is equal to 2019). You can expand this condition, adding more evaluation rules by clicking on "Add" button. In the advanced condition builder, this can be achieved by adding a "rule".

So you can add (Period is equal to 4). And you can link all two or more evaluation rules either with and AND operator, with an OR operator. Y if you want evaluation rule#1 AND evaluation rule#2 to be TRUE, then you use AND operator. If you want to evaluate if either evaluation rule#1 OR evaluation rule#2 are TRUE, then you use OR operator.

Now, the tricky part: what I understood is that you want also to evaluate if any of the rulesets is set to one (on your screenshot I see 8 rulesets). We can call this whole evaluation rule#3; and split it into subevaluation rules (one per ruleset). In the advanced condition builder, this can be achieved by adding a "group" of rules

So the whole expression shall be:

(evaluation rule#1) AND (evaluation rule#2) AND (evaluation rule#3)

And the way to declare evaluation rule#3 is:

(evaluation subrule#3.1 OR evaluation subrule#3.2 OR ... OR evaluation subrule#3.8)

The whole expression shall look like:

(evaluation rule#1) AND (evaluation rule#2) AND ((evaluation subrule#3.1 OR evaluation subrule#3.2 OR ... OR evaluation subrule#3.8))

THere is an excellent description of the advanced condition builder here:

https://flow.microsoft.com/en-us/blog/build-more-powerful-conditions-in-flows-and-more/

If you find confusing adding all this staff to your single "Condition 2" action block, you can use nested Condition action blocks.

Step#1: in "Condition 2" action block you evaluate (evaluation rule#1) AND (evaluation rule#2)

Step#2: add a "Condition 3" action block inside "Condition 2" true branch

Step#3: in "Condition 3" action block you evaluate (evaluation subrule#3.1 OR evaluation subrule#3.2 OR ... OR evaluation subrule#3.8)

Step#4: move "Send an Email" action block inside the "Condition 3" true branch

Hope this helps

That's the idea! Did it work?
Strictly speacking you do not need the "get a row" inside the loop, since it is already iterating over all the rows in the excel. But if current design works, then we can live with it unless the performance is too low

In this same screen, can you dobleclick on "get a row" and verify if the output is one of the rows you are looking for? Please note this is the result of one iteration, the evaluation failed so no email was sent for it.
You should be able to inspect the rest of the iterations also, let me find a screenshot to show you how to do it

hi @efialttes

I don't understand it that way.
As you mentioned, I have not yet created condition 3 because I do not understand where to insert it.

To return to your last question, it is true that values have been found, but why is there no mail sent?
(the intention is that if 1 in, for example, ruleset 1 is found, a mail is sent with the value from the column A + B + C)

Hi

On the same screen you shared to me (the one that shows last execution results) you can verify the number of iterations (that is, the number of rows evaluated) in the "Apply to each" action block:

Whenever any of the iterations fail, you will see a red icon on top right of the "Apply to each" action block. If all iterations succeded, then this icon will turn green.

You can inspect the iteration result one by one, just click on "Next>".

In the iteration example you shared, execution succeded. However, no email was not sent for that row because the evaluation of the condition returned 'false'. You can inspect the iterations one by one and verify if condition evaluation from any of the iterations returned 'true'. If so, then one email should be sent per iteration whose condition returned 'true'. If ten rows evaluation returned true, then 10 emails sent. If 0 rows evaluation returned true, then 0 emails sent.

Hope this helps

No, sorry, I don't understand.
I apologize for keeping you working.
The condition is that there is a 1 in a ruleset and so he must send the mail.

Thanks for shareing the info. On your screenshot you will see 8 iterations occur (your excel table has 8 rows, right?), and since the icon on the top right corner is in green, all of them succeded (meaning no execution error occured).

If no email was sent, this is because the flow evaluated the condition 8 times but all of them returned false.

From your previous posts it seems that at least one of the rows should return true, so let's see if we find the problem.

Can you open the editor and share a screenshot on how you defined "Get a row" inputs?

Also, in the same editor, how did you define the condition? I mean, did you use the outputs of "Get row"?

I think we got it!

Edit the condition, and instead of 2019 use the following expression:

string(2019)

You need to do the same with:

4 -> string(4)

1 -> string (1)

The reason for this is the following: when flow reads the Excel rows, it is most likely considering their column values as strings (text) instead of integers (numbers). So we need in the evaluation rules to compare to strings.

I did some testing by myself replicating your excel (I simplified it a bit, but the concept is the same), and it works!

So this is the first iteration output:

And this is the second iteration output:

Please also note you do not need the "Get row" action block if you select the condition evauation entries in this way:
