How the user interactions and relations work in sales line between item and inventory dimensions of sales table form. For example, if i select a item ( DimGroupId without configid and inventsizeid) then how automatically the fields of inventory dimensions disable/enable and inventdimid is filled. Please explain me on this.
Not sure I understand your question, but I feel the answer is the dimension group. Look at the dimension group associated with the item and see what is activated, then depending upon the setup these are required.
This is done with the help of InventDimCtrl_Frm_Mov* classes.
Have a look at the updateDesign method in the sales table form and try to bedug the code…
