SAP Where Filter with Power Apps variable

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.

Re: SAP Where Filter with Power Apps variable

I am not very familiar with SAP, but I will try to get a answer for you in the next days!!
I know that it was not possible to consume CDS Views out of the box, and we had to configure the ABAP that the Power Platform uses. This ABAP is called `RFC_BBP_READ_TABLE`. However, this function cannot consume CDS Views directly. To address this, we created a custom ABAP program. Now, when `RFC_BBP_READ_TABLE` tries to consume a CDS View, SAP redirects the request to our custom program, `Z_RFC_BBP_READ_TABLE`.

Re: SAP Where Filter with Power Apps variable

Thank you for your explanations. I know how to create the flow with Power app. However this is not what i am saying Read SAP Table as "Structure". Let me give an example - SAP Table has different type - Transparent Table, Structure, Database View, Project View.. We are ABLE to get SAP Table Transparent Table or Database View. However we CANNOT get SAP Table Structure.. That is what i am asking.. how to get SAP Structure in the flow? its possible or NOT? i think your AUFK Table is Transparent Table...

Re: SAP Where Filter with Power Apps variable

Sorry for the late reply. I hope i understand right and give you the answer:

You can create a Flow with the step with SAP and Function Read SAP table with parsing.

For example the AUFK Table:

You can edit what columns you want to get from SAP. When you execute this flow you will get the Table as JSON Array and it is structured.
All Columns will displayed in the sections Rows of this step:

If you want to use this Date in a Power App for example you have to give it back to the app:
Add a Step HTTP Response

And after you execute the flow ones just copy the Rows Json from the SAP step into the "Generate from sample" of the HTTP Response Step.

When you bring this flow in your app you are able to put the data in a Collection for example on Onstart or on a button control:

It will stored in a Collection and will remove after you close the App.

It is a Table but only with string columns.

When you only want to use the Data in Power Automate then you will find any Column / Row in the Rows Section of the Read SAP table with parsing output.

Re: SAP Where Filter with Power Apps variable

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.

Re: SAP Where Filter with Power Apps variable

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?

Re: SAP Where Filter with Power Apps variable

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 “.
