You can read from any Entity but you can only update the current Entity. You would have to loop round all the Entities that might be updated via the Text1 property, query the Entities that have the Text1 property (eg 30801_30800) and compare the Text1 property to the current Entity. If that is not practical then you might need to consider another way of doing it (XFSetValue in a Spreadsheet perhaps but that data is not flagged as calculated which might cause a problem). If this is a single value you might consider using an intercompany account in a central Entity. You calculate the central Entity first and that pulls the value into the IC account where the IC member is the source Entity. Then calculate the other Entities and they look up their value from the IC account in the central Entity.
