Data analysis in relatation to BSID and BSAD

[ITManuel]

Hi,

I'm building a report which analyses customer related accounting informations contained in BSID and BSAD. What I understood so far is that BSID contains open (non - cleared ) items and BSAD contains cleared items. 

I've discovered that the column [BELNR] cannot be used as a unique identifier for accounting documents. CHAT-GPT is saying that the unique identifier for accounting documents in BSID and BSAD is composite key of the following fields: [BUKRS], [KUNNR], [GJAHR] and [BELNR] this on a document basis on a line basis also [BUZEI] would need to be included. 

My first question would be, is this information correct?

My next question is in relation to the clearing items contained in the field [AUGBL]. This field seems to contain the [BELNR] of the clearing item, but the [BELNR] is again not unique across the tables. I find multiple items if I search for the clearing item with only the [BELNR] which is provided in the [AUGBL] field. 

How can I solve this issue or am I not getting something correctly?

Thanks in advance

Best regards

I've found that ChatGPT is often not correct when using SAP.

Why not use the BSEG table for this?

Or, if you are on S/4HANA, use the ACDOCA table?

Hi Tammy,

thank you for your response. 

I'm still working on S3 so would have to go with the BSEG table. Using this table I can ignore the BSID and BSAD table right?

I intend to use BKPF and BSEG and combine them to have all informations required. I understood that the unique identfier of a document in BKPF and BSEG is a composite key of the fields [MANDT], [BUKRS], [GJARH] & [BELNR]. Via this key I intend joining the the 2 tables. 

It is still not clear to me how I can intentify clearing items in BSEG. The field [AUGBL] seems to contain the [BELNR] of the clearing item, but the [BELNR] is again not unique in BSEG. I find multiple items if I search for the clearing item with only the [BELNR] which is provided in the [AUGBL] field. Would a composite key of [AUGBL] and [AUGDT] be a unique identifier?

If not how can I identify clearing items of individual items in BSEG?

Thanks in advance
