Error in subquery

Question

I have a table on which i need to generate serial number or batch numbers based on two criterias that by each unique desc, and item qty less than 10 per batch and item weight less than 50, i got the solution yesterday but when i rewrote the query using subquery it giving me an error like 'ora-01436' , how to overcome this problem.is there a way to write procedure and do this more simpler.please find below the sample test case.

Answer 1

Yeah i am sorry for posting it wrongly and i will brief it again in a proper way.
Thanks very much for the response alberto, will explain it again, actually i am generating the batch number or you can say serial number based on tmp_desc with two criterias of adding up the tmp_qty and adding up tmp_wt as follows.
Criteria for generating batch number is tmp_qty should not exceed 10 per each batch and tmp_wt should not exceed 50 each batch
Conditions
a) New batch number will be generated with max(batch)+1 from os_batch for every combination of tmp_Desc and till tmp_wt reaches 50 and till tmp_qty reaches 10, in simple each batch must not contain tmp_wt more than 50 and tmp_qty not more than 10 per each tmp_desc.
b) if weight exceed more than 50 for example if its 60 and qty is 10 , two batches will be created with weight as 30 30 each
as the wt criteria is more and it takes the priority.
c) if wight is ok that is less than 50 like 25 and qty is 50 then 50/10 that is 5 batches will be created with weight of batch being 5 and qty being 10.
d) if both the cases come together like wt is 60 and qty is 50 , priority goes to qty and it will 50/10 -- 5 batches with 60/5 wt per each batch.
please let know if you have any more clarification.
