First time I've ever reached out to a support community for help, really hoping someone can provide some direction (that I can understand).
Scenario: I have a primary/master SP list that I am using to store general information about contracts, each list item has a unique CONTRACT-00XX identifier. I have multiple secondary lists that contain other information about the contracts and they also contain the same unique CONTRACT-00XX keys. (Because of the column limits I need to use multiple lists). When a user needs to update their information I have them utilize the editifs.aspx form for the item in the master list.
Desired Result - the editifs.aspx form for the master list item displays secondary list data for CONTRACT-00XX item.
1. Editifs.aspx form retrieve data from secondary lists based on the CONTRACT-00XX key. (I have accomplished this - I can get the data fields from secondary lists with the values as they exist in secondary source)
2. On Form Submittal/Save have the secondary list fields submit back to their respective list items (key = CONTRACT-00XX) with any changes the user may have made to the secondary data fields. This is where I am struggling.
Hopefully this question makes sense. Thank you in advance for any help!
