Input form

Please help me to achieve this. i have created both table and link cus:dataOwnerMapping with nms:service but when i add dataOwnerId filed in form and add new form data it not allowed me to update the cus:dataOwnerMapping  table with serviceId and dataOwnerId. nms:service table PK should be save as serviceId in cus:dataOwnerMapping  with dataOwnerId.   

• AC data model:
  • create a new table cus:dataOwnerMapping containing the serviceId + dataOwnerId
  • create a new table cus:dataOwner containing the dataOwner information: dataOwnerId, GPN, firstName, lastName etc
• AC form changes:
  • enhance current AC service form to contain a new tab for adding and deleting data owners: linklist element for the link to the cus:dataOwnerMapping table
  • the pop-up with the addition/deletion of data owners would contain data owners which would be recipients fetched from the internal recipients folder (conditions to be added accordingly in the form)
