We have an inbound MATMAS IDOC configured. During updates on existing materials, only some fields are populated in the IDOC. This is causing a problem for the numeric fields like the weight fields MARA-BRGEW/NTGEW and the volume/height/width fields if they are not sent in the IDOC. They are passed as '0.00' in the 'MATERIAL_MAINTAIN_DARK' FM and end up overwriting the existing values with '0.00'. For character fields, we are overcoming this by passing '/' if the field is empty, but not sure what to do for numeric fields. Kindly provide your valuable inputs.
