Problems updating MARM table using bapi_material_save_data

[former_member598938]

I need to do a mass update to the "EA" unit of measure record in my MARM table. I am new to ABAP and my code is not working. Can someone review and tell me what I have done wrong.

I have written the program to run from select parameters for starters, when this works I will replace with a table to update all my UOM's.

DATA: BEGIN OF it_unitsofmeasure OCCURS 0.

INCLUDE STRUCTURE bapi_marm.

DATA: END OF it_unitsofmeasure.

DATA: BEGIN OF it_unitsofmeasurex OCCURS 0.

INCLUDE STRUCTURE bapi_marmx.

DATA: END OF it_unitsofmeasurex.

DATA: BEGIN OF wa_bapimathead.

INCLUDE STRUCTURE bapimathead.

DATA: END OF wa_bapimathead.

DATA: BEGIN OF IT_BAPIRET2.

INCLUDE STRUCTURE BAPIRET2.

DATA: END OF IT_BAPIRET2.

PARAMETER: zmat LIKE bapimathead-material.

PARAMETER: zalt LIKE bapi_marm-alt_unit.

PARAMETER: znum LIKE bapi_marm-numerator.

PARAMETER: zden LIKE bapi_marm-denominatr.

wa_bapimathead-material = zmat.

it_unitsofmeasure-alt_unit = zalt.

it_unitsofmeasure-numerator = znum.

it_unitsofmeasure-denominatr = zden.

it_unitsofmeasureX-alt_unit = 'EA'.

it_unitsofmeasureX-numerator = 'X'.

it_unitsofmeasureX-denominatr = 'X'.

APPEND it_unitsofmeasure.

APPEND it_unitsofmeasurex.

Change this

wa_bapimathead-material = zmat.

it_unitsofmeasure-alt_unit = zalt.

it_unitsofmeasure-numerator = znum.

it_unitsofmeasure-denominatr = zden.

it_unitsofmeasureX-alt_unit = zalt.

it_unitsofmeasureX-numerator = 'X'.

it_unitsofmeasureX-denominatr = 'X'.

in function call

tables
unitsofmeasure = it_unitsofmeasure[]
unitsofmeasurex = it_unitsofmeasurex[]

thank you for your help, I added the changes, but it still did not work. I printed out the IT_BAPIRET2 return and it says my my material was created or extended.

Maybe I am mistaken, but I should be able to update an existing EA record with the new denom and numerator, correct? If so, am I using the commit FM incorrectly?

I am closing this thread, the problem was I had not selected at least one view in the mathead. Once I selected Basic_view, the unit of measure updated. Thanks for all your help
