Adding Tab and Field in MIGO
Im recently new in programming in ABAP, and i have been asked to add a new Tabstrip at details level with a new field type MSEG-LLIEF.
I've created a BAPI implementation of MB_MIGO_BADI and copied the example code, I have been analyzing it carefully and also noticed that a field LLIEF already exists in the GOITEM structure. The tab and field for the user to fill must also appear only if the document is of movement 911 (BWART = '911'), it has to have a matchcode to table LFA1 (The Provider must exist in this table) and it must then be saved in field MSEG-LLIEF where MSEG-ZEILE = '0001'. My question is where to go from this point, cause im kinda lost.
