You need to create 2 DMIS programs. One to datum the fixture FIXTURE.DMI, one to inspect the part PART.DMI. Once FIXTURE.DMI has constructed the datum use SAVE/D(label) to save the datum. This makes the datum available to all other DMIS programs.

In the PART.DMI program issue the statement, RECALL/D(label). This will recall the saved datum.

This allows you to datum the fixture once and inspect many parts.

Note, a datum created in a program, for example, D(label)=TRANS/XORIG,10 can be recalled by RECALL/D(label) without being saved as it is local to the program.

In summary, use SAVE to publish the datum to other programs.
