I am using SDK tool for adding extension field and I have got one sap tenant system(for ex. system number is111) and more than one user id and password but when i adds extension field from user U1 in one solution and creates another solution with same user in same system no ie. 111 but when I save and activate first solution and check the changes in sap tenant system then it shows the extension fields but agin if i opens solution 2 and activates it then extention fields created in solution 1 get diminished and if again i open solution 1 then it stars appearing but fields created in solution 2 gets diminished.
and also the problem is if I have created solution from machine 1 and want to edit it from machine 3 then it says solution is locked by user "XXX".
How to solve this issue. It means SDK is USER specific? system specific? machine specific?
