Dear Experts,

I want to give an error message in TC f-43.

When i am giving the document date,posting date,reference,account number it is posting.But when i am changing only the document date with same reference number and account number it again posted.Here i want an error message that 'the bill number is already exist'.

Please suggest your advise.

Thanks & Regards,

You need to Debug the Code and Find out the User-exit where you can write your code to Raise Error message.

Already i debug in this.But i cant found any user exit.I checked all the user exits one by one but the debugging couldn't on any where.

Can you please specify me the perticular user exit in which i can write the code.

Hi shilpa did u try this Enhancement F180A001 / EXIT_SAPLF048_001 Financial Statement Adjustment Exit


You can also try one of the BTE's and check .. go to FIBF .. there you will get the Business transaction Exits for all transactions

I will give some of the BTE's here which i find relevant ..

00001020 POST DOCUMENT: Prior to final checks -- This triggers on Save Button

00001010 POST DOCUMENT: Check customer line item -- This triggers on Customer Line item when you press enter key

00001011 POST DOCUMENT: Checks at line item level --- This Triggers for all line items when enter key is pressed.

00002221 DOCUMENT POSTING : Payment Release (Line Item).

In a BTE you can post your own code so that it executes prior to final processing ..

best Regards

Hi ,

Thanks a lot for your suggetion.I got the solution,but the BTE is "00001110" ARGENT_PROCESS_00001110.

From this i did a copy function module and than wrote code in this and attached it in this particular BTE.

It is not nessary to change the f-43 transaction. Ask the help of your functional consultant to create a new validation
