Limit the value of the "To Transact" field

Hi,

In the module:
Supply Chain Execution > Work Execution > Task > Execute Production >

"REVIEW DISPATCH LIST > COMPLETE WITH DETAILS > BACKFLUSH MATERIALS" we need that the field "*To Transact" be less or equal the field "Required".

Through the Page Composer, we can observe in MAXIMUM the following expression:

#{(row.TransactionTypeCode eq 'MATERIAL_NEGATIVE_RETURN') ? 0 : ((row.TransactionTypeCode eq 'MATERIAL_RETURN') and ('Y' ne pageFlowScope.parameterMap.isOrderLessFlowFlag)) ? row.PreviouslyIssuedQuantity : (row.SerialNumberControlCode ne 1) ? 1 : null}

And in the required, we have this expression:

#{(row.SerialNumberControlCode ne 1 and row.IsAdHocComponent eq false) ? 1 : (row.IsAdHocComponent) ? 0: row.RequiredQuantity}



QUESTIONS:

1. Can you help me how can I make this personalization in the page?
