ASSERTION_FAILED dump error when using SD_VBUP_READ_FROM_DOC_MULTI

[walkerist]

I am experiencing ASSERTION_FAILED dump error when running my code.

Here's my code:

   DATA: lt_vbuk_key TYPE vbuk_key_tab, 
         lt_vbup_key TYPE vbup_key_tab,
         lt_vbup     TYPE vbup_t.
INSERT VALUE #( VBELN = TVBDPL-VBELN ) INTO TABLE LT_VBUK_KEY.
INSERT VALUE #( VBELN = TVBDPL-VBELN
                POSNR = TVBDPL-POSNR) INTO TABLE LT_VBUP_KEY.
  CALL FUNCTION 'SD_VBUP_READ_FROM_DOC_MULTI'
    EXPORTING
      it_vbuk_key               = lt_vbuk_key
      it_vbup_key               = lt_vbup_key
    IMPORTING
      et_vbup                   = lt_vbup
    EXCEPTIONS
      vbeln_not_found           = 1
      vbtyp_not_supported       = 2
      vbobj_not_supported       = 3
      OTHERS                    = 4.

There's something wrong in the CALL FUNCTION parameters, I guess... a failed assertion is a termination used (in this case) by SAP to prevent further data movements.

Check the DUMP analysis, program details: you will find a line like

>>> assert 1 = 2.

Read the code BEFORE that point, I guess you will find an IF. That's the wrong data detection.

The FM fills internal table of type VBUP out of table VBUP
-for all items of given SD documents, if it_vbuK_key is provided

-for given items of given SD documents, if it_vbuP_key is provided

But :it's not allowed to provide both tables.

You must decide, if you want to get the status of all items of a document or the status of specific items only.

Basically

  ASSERT it_vbup_key IS NOT INITIAL AND it_vbuk_key IS INITIAL OR
         it_vbup_key IS INITIAL AND it_vbuk_key IS NOT INITIAL.

So either you pass keys of a list of items or keys of a list of documents, not both. If you pass only keys of documents, it will select every item of those documents.
