Custom MARA Field Update in VC7.0 SP13 - Extensionin and Extensioninx .

Hi All - Material Master Update Question

We currently have a "cockpit" set up in VC to Edit Material Master data in a table & this works perfectly

for standard fields in MARA. using BAPI_MATERIAL_SAVEREPLICA .

We now want to be able to update "cutom fields" in MARA that we have created

We have written our own select BAPI to select the data into a table but are struggling with the update portion.

Does anyone have experiece in how to do this in Visual Composer.

We think the solution is to use Extensionin and Extensioninx Fields.

i.e. a guide on How to setup Extensionin and Extensioninx Fields in Visual Composer to update Material master Custom fields

Using BAPI_MATERIAL_SAVEREPLICA

Any help would be appreciated.

Thanks,

Robert
