Whist trying a simple patch function in Apps I am getting this error. I am using a checkbox and the code for OnCheck is as follows:
Patch(DespatchLines_1, Defaults(DespatchLines_1), {Despatch_RMA:ThisItem.RMAAutoNo, Despatch_PN:ThisItem.Product, Despatch_PO:ThisItem.'PO#', Despatch_Serial:ThisItem.'Serial #',Despatch_Desc:ThisItem.'Product Description' ,DespatchL_RDN:Header.LastSubmit.Despatch_No})
The strange thing is that I am using an almost identical function in another app and that works fine.
Looking forward to your help.
Simon
