Hi guys , Its really good to use multiple Company Datas in Lookup.
Here i have designed for this solution..
1.Created one New Tabled called SaadLookpUp. which contains the field of String Data Type which EDT as Name
2. Created one New Form called SaadMultiCompLookUp. here i have used this form for bulding LookUp
added new datasource with the Table of SaadLookpUp and set CrossCompanyAutoQuery to Yes.
More Reference for creating Form_LookuP
3. Created one new EDT called SaadMultiCompLookUp and set FormHelp to SaadMultiCompLookUp
4. Created another Form called SaadOutputMultiComp , in this form i have shown two way of retrieving Names, one way is showing All Company Names and another way is showing Names from the selected Company. .
Created one String Control in Design node of this form called Name and set ExtendedDataType as SaadMultiCompLookUp.
