I'm trying to do the invoke of IC44 within my new custom BI145 (clone of IC145) program. I am only passing the company, location and item to IC44, along with the Function Code of "I" (Inquire) but I am getting back an error of "Cannot Insert On Blank Key". I have no idea what this means. I didn't think IC44 was doing any kind of updates? I am just trying to do an inquire and then grab the Current Days Stock and Hand and Current Average Daily Usage and move those values to my new report. What am I missing? Are there other fields I should be populating before I do my invoke? I really appreciate any help - thanks in advance! This is a high priority report for Pandemic reporting.
