Hi,
There is a Cross Reference Tool within JDE/Peoplesoft E1, that allows you to find everywhere the data item, MCU2 is used. Assuming that the Cross Reference Relations have been "built" in your environment, you can access this Tool by going to:
> Foundation
> Tools
> Cross Application Development Tools
> Cross Reference Facility
If you want to see all Tables with the field MCU2, you would click on the option "Tables Using a Data Item", under the "Data Items Tab". Type in MCU2 in the Data Item field, and it will show you all Tables with MCU2.
If you want to see all Programs/Forms with the field, MCU2, you would click on the option "Forms Using a Data Item", under the "Data Items Tab". Type in MCU2 in the Data Item field, and it will show you all Programs/Forms with MCU2.
Note, if the Cross Reference Relationships haven't been built, you can build them by choosing the "Rebuild Relationship" option on the Form Exit Bar, but you may want to check with your IT Dept before you run this.
