Hi,
If you already know the ID of the TG, you can directly loop at table CRMD_MKTTG_TG_H with
this TG ID to find out the TG's GUID. Because table CRMD_MKTTG_TG_H has a field called ID to
store the TG's ID.
After you got the TG GUID, you can use this GUID to access the items in table CRMD_MKTTG_TG_I.
Best regards,
Henry
