I would like to retain the values/records in the detail when i click on + sign (Add record in the detail) into the modal pop-up of multiselect lookup.
STEP 1: I'm using a multiselect lookup object and selecting couple of values on Add Record of a detail (i.e., clicking + sign)
STEP 2 : After selecting values from step 1, when i click + sign again, i would like to retain the values available in the detail grid to the modal popup with the checkbox selected.
STEP 3 : The multiselect lookup's modal pop-up should be like this.
when one of the selected value in STEP 1 (ex., incoming document 1) is unchecked and a new value is selected (ex., Regulation 3) the insertion should act accordingly.
Incoming Document 1 --> Should be removed from detail (since its value is unchecked now)
Minutes 2 --> should be available in the detail (since already selected in STEP 1)
Regulation 3 --> Should be added to the detail.
Kindly guide to achieve the above!
Thanks in advance!
