Most models allow you to set a department price. Try that

I assume you mean flat departments or PLUs (ones on the keyboard).
Turn key to program 1 SUBTOTAL 0 Flat dept or PLU SUBTOTAL

Hi. The previous owner just had PLUs linked to the depts that suited them. to link PLUs to depts,
Turn key to Program mode.
3 SUBTOTAL
1166 SUBTOTAL
Now type the PLU number you want to link. E.g if you want to link PLU 6, then press 6 on the number pad (don't press the actual PLU, just type its number on the number pad)
Now press the button marked PLU. It should be near the other function buttons.
Now type the department number to link to. Use two digits. E.g to link to dept 5, type 05 on the number pad.
Press CASH
Press SUBTOTAL
As for NO SALE button, does it actually show the command NO SALE, or NS on the display when you press it? It may have been removed from the keyboard. Does the drawer open when you finish a sale normally?
There is normally a setting in key features for VAT breakdown on the CASH button. Make sure this is set so that it prints the breakdown. Add on means you sell at a tax exclusive price and the tax is added on to that by the register. Add in means you sell at a tax inclusive price and want the register to show how much of it was tax.
Hope this helps. See how you get on.

how do I fix error E32 on cash sharp resgister XE-A21S?

Hi. You have been given the wrong instructions. That is why it is now all screwed up. Pricing is dead easy. You have condiments setup because you have set key features in prog 3 mode. It shouldn't be too hard to fix. We'll start with prices: Turn key to Program mode Type the price (no decimal point) Press a PLU (item button) to set the price to. Press SUBTOTAL To remove condiments, you need prog 3 mode. While key is on program, press 3 then SUBTOTAL. The display must change to "P3" Now press 0 (zero) then one of the PLUs that has condiments set. Press SUBTOTAL to finish. It may remove the tax status, so turn back to REG mode and test the PLU. If the tax has gone, then reprogram the tax setting for that PLU. Let me know if you get stuck. Mark

See my other answer.

take a readout of the department and groups first
pgm6
205 subtotal
1 cash 30 cash
this will print out your departments

pgm6
206 subtotal
this will print out your groups

pgm3
1166 subtotal
enter your 6 digit number then press all the products linked to that department / group

your 6 digit number = DDGG00 DD= Department GG= Group
then 00
so for dept 1 gp 1 = 010100

when finished
press subtotal

Hi. I'm afraid this is not a 'basic requirement' of a cash register. You are working with a very complicated area of cash registers that only the medium to high end machines can even do. If you are getting stuck already, then you will not be able to work out the more complex batch processing areas of scanning either.
Your dealer should have setup the majority of this for you before you left their store (especially the keyboard layout issue and keysheet for the keyboard), then you would normally receive extensive training if you are going to be making program changes yourself in future.
You will need to learn about the difference between flat PLUs and scanning PLUs, 'Not found PLUs' like you have run into so far, then deletion techniques, PLU status programming, manual entry using OBR method etc. The book is only a guide to what you should have learnt during training. You really need to go back to the dealer and get a training session. They should be able to sort out all of these problems for you. It will take a one on one demo to fully train the ins and outs of full scanning systems.
