CIM Loads are used in QAD's MFG/Pro. It's worth asking on that forum as well.
You use a CIM Load to start up a menu option in MFG/Pro then load data into that menu option using a pre-generated text file containing commands.
So, what you have to do is:
1. Determine what data you want to load into MFG/Pro.
2. Create a CIM Load file using that data.
3. Load the CIM File into MFG/Pro.
The advantage of using a CIM Load over a normal Progress Data Load is that a CIM Load uses the functionality of the Menu Option, so performs whatever other processing that is carried out by the program.
The disadvantage of a CIM Load is that the loading file can be a bit fiddly and you have to get the parameters exactly right.
I believe you can transfer an Excel Spreadsheet into a CIM Load, but I've never done it myself.
If you ask again on the QAD MFG/Pro forum then some experts will be able to help.
