an error occurred when attempting to retrieve a value

[dzimmerman]

in one of my applications i have a form with a field that is optional for the user to enter. we are getting a lot of warning messages on the "errors" section of valence. how can i setup this program so we dont get the warning message. when trying to retrieve the value...

I assume you are using NAB and that this is based off one of the EXNABBTN template program? If so, you can toggle gWriteErrLog variable *on and *off. So in your case, you would want to set it to *off before calling the procedure to retrieve the value...you can turn it back *on if need be afterwards if you wish.

perfect. that is what i need. thanks

I added the below code into my rpg program. However, when i look at the warnings i am still seeing : VV00070 - An error occurred when attempting to retrieve a value for "PRODSCH".

gWriteErrLog = *Off;
UserInput.ProdSched = GetFormChar(cFormProdSch);
gWriteErrLog = *On;

Sorry, disregard my prior post - I see you're using GetFormChar(). That should definitely be skipping the exception message when gWriteErrLog is *off. If you still see the message being written, let us know.
