What is purchLine_ds in purch table from?


In puchtable form–>DataSources–>purchline–>Fields–>LineAmount–>Modified methods is there as bellow

void modified()


My doubts is what is purchLine_ds?

It references the FormDataSource.

By using this you can override the method of the FormDataSource Class based on your requirement…(The methods you can override can be seen in override method of the form data source)

In the Above method - It actually calling the active method of the PurchLine formdatasource when the field is modified…
