Error while updating Sales Order : Another user Modified Table (RDR1 )

Question

Hi All,
I am getting an error message while running the following steps.
Steps
1)     Pull an entry from sales order.
2)     Add new data to line.
3)     Update the sales order.
a)     Sap updated the data.
b)     Through code using DI API we updated some UDF.
4)     With out closing / Pressing OK button…
5)     We added new data to line.
6)     Then Press update.
An Error will through by B1 as “Another user modified the table(RDR1 ).” Before going to the code where we are handling the update of UDF.
But after the 3rd step above when we do
4) Close the window or pressed ok
5)  take the sales order window again pull the data
6) Add new Data to line.
7) Update sales order then it will go smoothly.(Updating by B1 and from code )
Can anybody tell me why this happens?And any workarounds to solve this?

Answer 1

are u adding a matrix row thru the code? I get this error when I am adding rows and I get the rownumber out of sync.
if so get the max (lineid) from rdr1 and then check against the matrix.rowcount before adding a row. if lineid is greater that matrix.rowcount take lineid + 1 and assign it to the matrix.row, else take the rowcount + 1
if not, and as a workaround, then you can try using the SBO_SP_transactionnotification stored procedure.
