I'm having problems with tdsls4810s000. I have custom code that will change tdsls040.pcpr - Customer for Prices/Discount. When this field changes the lines should get a 27% discount vs the 50% the order was correctly created at. After the change I set tdsls040.orno and zoom to tdsls4810s000 and it will not recalculate the lines. Is there something that I need to set to trip the recalc session into looking at the header and all lines?

Do you own source code? Then you could look at tdsls4810s000 to see what needs to be set to recalc session into looking at the header and lines. I am not familiar with this session and do not know how it works. Just making a suggestion since sometimes you have to get the session called correctly.
