CALL_FB08: FM to Reverse an Accounting Entry in FB08

Have you ever searched for the BAPI or FM to post the reversal accounting entry and still not found anything substantial? If yes, then this post is related to the same topic. Today, I will show you how you can use the Function Module or CALL_FB08 FM to reverse an accounting entry in FB08.

I’m sure when you googled it, you would have found a couple of BAPI’s. For example, BAPI_ACC_DOCUMENT_REV_POST and BAPI_ACC_GL_POSTING_REV_POST. But, if you try to reverse an accounting document using these BAPI’s, it gives an error. It is because accounting document reversal is not meant to be reversed by a BAPI. These BAPI’s can be used to reverse only those accounting documents that were posted using a BAPI itself, e.g., BAPI_ACC_DOCUMENT_POST.

If you have used BAPI_ACC_DOCUMENT_POST to post any accounting entry in the system, then you can definitely use the reversal BAPI to post the reversal entry. But, if you post any Financial accounting document manually in the system, then these reversals BAPI’s will not work. In that case, you need to use the Function Module CALL_FB08.

CALL_FB08: FM to Reverse an Accounting Entry

Using the CALL_FB08 Function Module is fairly easy. It is very similar to executing the FB08 transaction. When you execute t-code FB08, you enter the document number, company code, fiscal year, and reversal reason. These details identify the accounting document to reverse.

Similarly, in the FM CALL_FB08, you define only these 4 fields. Without taking much time, let’s get right into it!

Step 1: Post the Accounting Document to be Reversed

First of all, you should have an existing accounting document that you want to reverse. If you don’t know how to post an accounting document in SAP, then you may go through this tutorial on F-02.

In this example, I have posted a customer invoice of $5000 using FB70. The document number is 1400000023, company code 1234, and fiscal year is 2021. I have used the current date, i.e., 26th April 2021 as the posting date.

Step 3: Enter the Details in FM to reverse an accounting entry

In this step, you need to enter the details of the accounting document to be reversed. The fields I_BUKRS, I_BELNR, I_GJAHR, and I_STGRD are mandatory and you must fill them in before executing the FM. The rest of the fields are optional and can be left blank. Please enter the following data in these fields:

  • I_BUKRS = Company Code
  • I_BELNR = Document Number to be Reversed
  • I_GJAHR = Fiscal Year of the Document to be Reversed
  • I_STGRD = Reversal Reason (Same as you mention on the FB08 selection screen)

As can be seen in the screenshot above, I have given the company code 1234, document number 1400000023, the fiscal year 2021, and Reversal Reason 01 (Reversal in Current Period). If you want, you can also specify the posting date of the reversal document in the I_BUDAT field. If you keep it blank, then the system will automatically determine the posting date of the document to be reversed and use it as the posting date in the reversal document.

After entering these 4 fields, you can click on the ‘Execute‘ button to process the post the reversal accounting entry. You will get a notification of the reversal document number. In this example, the system has posted a reversal accounting document number 1600000092.
