Access 2010: Merge Database with the same structure

You can assign to every user's base some unique number, which will be added to main DB.
For example: First user will have ID =1, Second - 2 etc.
Main table should have index form this ID (user) and record ID.
Example have 2 tables and 2 append queries. You can also update records, if you like it with update queries

Yup thats correct however as I wrote cant use append (or ammend :P ) queries cause I have multipple input fields. Besides Id like to join 2 separate databases not tables if possible.
Looking for VBA automation

May be you can show example of your Dbs? What is joining of databeses? Usually joining means adding data from "user's" databases to "central".
You can use code from your example for automation, but you should prepare data for joining.

thats my first project in Access so sry if I didnt explain correctly.
So by prepare data for joining do you mean linking databases?

No, I mean adding some unique IDs for identification of source DB. If you have many tables - you should add these two fields (user ID and Record ID) to every table in main DB.

I can't understand how you can copy/paste data from user DB to main. You shoud also correct references i¿ you have some autonumber IDs

right, imagine one of my engineers wants to work from home this week. As I cant get server, I send him an empty database (empty copy of master) so that he could type in another strategy in it. When he finish he send it back to me and Id merge it with master one.
So id have to copy all existing rows from all tables in his version to master (no dupes) starting from one row in master table 'textbox'

I think you could have too many problems with this approach.
For example:
During homework user will add some new records to table textbox and then delete one or more (let Strategy will be 10,11,13,15). In all other tables you have reference to this table. When you are adding data to main table, autonumber field will be (if your textbox table will be unchanged) 10,11,12,13. But references in other tables will be unchanged and you should have method for correcting them. And you will always have problems when home users will be more then one.

users get a form with empty database and they add one strategy per their form/database eg one main primary key in textbox. There is no autonumber - primary key is equal to unique predefined strategy number.
Im sure there is a way to connect via ADODB or something just to copy all rows from one database to another one /no dupes/

It is not a problem, if references will not be changed.
Can you upload empty DB (central) with tables and another one with one strategy filled (with sample data)?

didnt upload any pics but commented them out

cheers

thanks for help. Ill analyse it tomorrow. Any idea how else could I sort out my lookup fields?

This is not pure lookup, but multivalued field - Failure modes covered - in table Maintenance Activities. Are you sure it is nesessary? You can't use such field in append or update query.

OK thanks. looks good. Could you show me on one of those tables how would you do sort out lookup field using separate table? Or should I start a new question?

Due to EE rules you should start new question.
But, as I've mentioned in last comment, problem is in multivalued lookup fields, not in simple lookup fields.
You can sort values in form without doing it in table.
