You can use the following fields as target fields in an assignment rule:
An assignment rule can have up to six target fields. Thus, using an assignment rule with all six costing keys KALAW1, KALAW2, ..., KALAW6 as target fields, you can assign up to six costing keys at the same time.
If you use an assignment rule to determine the valuation plant (field GLOBAL-WERKS ) or error handling rule (field GLOBAL-XMES_FLAG), this reduces the number of KALAW(1-6) fields you can include in that assignment rule accordingly.
With table lookups, you can only use target fields of the type USERTEMP (work fields) and Plant used for reading cost estimates (valuation plant).
With enhancements, you can also supply the field Valuation type ( the field GLOABL-BWTAR).
To maintain the field attributes of the target fields, choose the "==>..." pushbutton.
