Hello!
Sorry, for late reply!
I've once again checked a lot of your previous posts and I've found the screen with the table FEBRE and the actual layout of your bank statement. It seems to me that I've finally understood what is the cause of the problem with your bank statement.
As you can see from the screenshot of your bank statement, fixed text COMISION for external business transaction code 035 is in the subfield ?20 (?20/EI/1837616 IVA COMISION). Therefore, you can find the word COMISION in the table FEBRE. Thus, the interpretation mechanism behind the EBS could identify this word and trigger posting to alternative cost center.
On the other hand, fixed texts used for definition of search string for external BTCs 878 and 928 (00COMISSION and 00COMMISSION) can be found in the subfield ?00 (see the picture attached).
I've checked once again my notes and found the following. Information that is stored in this subfield of the field 86 does not transmit the actual note to payee. It is used to describe the transaction type (e.g. comision, incoming payment, outgoing payment or DEBIT BY INSTRUCTION for your 035 BTC) and during the upload this subfield is not regarded as note to payee. The information from this field is stored in another table, namely in the table FEBEP-BUTXT (EBS line items). In technical terms, this field is called Posting text. Please, refer to attached picture and check your own table for this field.
Thus, when you change your settings the way you did in your previous post from May 31, 2014 2:01 PM (Re: Definition of Search string to post Bank Charges to different Cost center, but when Cost element is the same.), you insert additional text (00DEBIT BY INSTRUCTION?20/EI/1837616) and thus place the fixed texts used for definition of search string in the subfield ?20, where it is regarded as note to payee text.
Unfortunately, as it seems, you cannot use the information from this field for definition of search string. Therefore, you will have to use user-exits as suggested by Ajeesh.
Hope, this will resolve your problems.
Best regards!
