If your Mercator system will be sending data to or reading data from an R/3 IDoc, you do not have to manually build the Type Tree. Instead, SAP provides a transaction for exporting an IDoc file, and Mercator has a wizard for importing the IDoc file. Using this method will greatly simplify your development process.
1. Import the IDoc from SAP to your Application drive.
a. Open SAP GUI and go to transaction WE63.
b. Select the appropriate Basic type or Enhancement.
c. Make sure the Control, Data, and Status Record checkboxes are selected.
d. Click the Parser button.
e. When the IDoc returns, go to System -> List -> Save -> Local File.
f. Select unconverted and click the Continue icon.
g. Save the file to Development folder and then your team’s folder as appropriate. A good practice is to name the file with the
Example: MATMAS03.ido
h. Click the Transfer button.
2. When the transfer is complete, open Mercator Type Designer.
a. Select “Import a type tree” and click OK.
Note: If you already have the Type Designer open, select the Tree menu then Import.
b. Import from R/3:IDOC and click Next.
c. Choose the correct operating system as appropriate. Click Next.
d. The character set is Native. Click Next.
e. The IDoc type is ALE. Click Next.
f. Save the file to the same location and file name as in step 1.f above. This time the extension will be .mtt. Click Next.
g. When the import is done processing, click Finish.
h. You do not need to make any changes to the type tree.
