I've read very carefully the whole documentation to BAPI_MATERIAL_SAVEDATA.
I am passing gross weight to MARM and it is saved correctly, but Gross Weight is still empty when I check my material in MM03 in tap Basic Data 1. Saved data is shown only in "Additional Data"->"Units of measure".
I wondered whether some other hidden field for Gross Weight, Volume and Volume Unit exists in other table or structure, so that I can fill in the textfield in tap Basic Data 1. At least it is not mentioned in the description.
Perhaps somebody else knows the solution? Please help.
Looking forward your answer.
