Executing the code only if modifaction of table comes from particular form

Hi all

I have one table suppose Project , for that project responsible employee is may be from different company . If we change any thing Project card other than dimension then financial dimension then it should execute company validate(whether he is from particularly company or other ) in some other class other wise it should not execute validate(skip validation) which is achieved using orig function

Now another condition is that validation execution skipping is done only if financial dimension is modified from that particular form. If financial dimension modification is done from another form then validation code should execute
