SAP Where Filter with Power Apps variable

(0) Share

Posted on by Pokke

Dear all,

my Usecase and Problem is the following:

I have a collection in Power Apps with values. I chain these values with the concat command to get a string that I can use as a Where Filter in Power Automate. Variable out of Power Apps:

Problem:

The variable is displayed correctly in the overview in Power Automate, but the unformatted display contains exit characters that SAP does not accept.

Formatted output:

unformatted output (with Exitcharacters):

Error Massage: The calculated length of the value for the field exceeds the allowed value length.

Important hint:

If I copy the string directly out of the Power App, copy the Where Filter directly into it, and enclose with [], the flow will run through and return the correct data to me. But the copied string does not contain escape characters either.

What am I doing wrong? I've tried attaching the string to an array before, but it also doesn't work because the exit characters remain.

Hello @Pokke -

My suggestion would be to create an array of the filters instead of building a long string.

This way the data types map cleanly to the Read Table function where-filter parameter. So instead of an array that contains a single string with all of your filters, build an array that has multiples values like so:

[
"VBELN EQ '123'",
"OR VBELN EQ '456'"
]

Cheers,
Scott

I tried it on the following way and it worked:
With the string out of Power Apps:
1.
2.
replace(first(body('Auswählen')),'OR ','')
3.
union(outputs('Verfassen_2'),take(skip(body('Auswählen'),1),sub(length(body('Auswählen')),1)))

4. Where filter of SAP = Output of "Verfassen"

I think this is not the best way but it worked. Also this i can go this way for all the other Apps i plan to do.

How about filter multiple in one column? for example each 1000 materials in filters. However its not working due to length 72 only.

There is a way to filter multiple values in one column. I found a solution in the SAP Procurement Template from Microsoft and SAP:

SAP Procurement template for Power Platform - Power Platform | Microsoft Learn

It is in the Flow "ReadPurchaseOrderList".

First Step:
Parse List from former SAP Step.
2. Step Prepare IN Statement:
concat('''',item()?['VendorRaw'],'''',',')

3. Step Finalize IN Statement:
union(json('["LIFNR IN ("]'), body('Prepare_IN_Statement'), json('[")"]'))

Last Step:
Maybe you import this solution in your tenant and have a look in this flow.

Hope this will help you! But i think this solution is very slow!

its not working as per your advice. its still error due to "the allowed value length is '72'. For fields of type byte array the value is base64 encoded and the decoded array length is used for length limit check."

I don't know whether errors can occur due to the language setting. Just to be on the safe side, I work in Germany and have all settings set to German.
The following IN statement works for me and looks like this:

[
"LIFNR IN (",
"'00000XXXXX',",
"'00000YYYYY',",
")"
]

Here are pictures:
The limitation of 72 characters can be avoided by the correct use of , and “.

ok thanks for sharing the screen. Are you talking about Language in SAP System. for Example {"AppServerHost": "XXXX","Client":"XX","SystemNumber":"XX","LogonType":"ApplicationServer", "Language" :"DE"} correct?

sorry, please go back to the start. You want to search for several materials (probably material number) in one column and then filter. Is that correct?

If this is the case, you can actually enter the individual materials in the WHERE filter as follows:

As already mentioned, this works in the procurement template.

yes this is correct, however its stuck like Several retries occurred if we added this like your compose else would get failed. Without this, its working i mean filters two material only.
