1. SD
2. MM

In SAP FI Integeration with other modules means how the 
system maps with different modules and how the effect of 
those is passed into FI Module.

SD will interact with FI, MM will interact with SD :- 

Looking at MM and SD interaction first, take the scenario 
of a third party order process. This process uses a 
purchase order (which is sent to your vendor). Also invoice 
verification is used further along the process to check 
that the invoice you send to your customer is the same 
material and quantity as that which the vendor sends to you 

Billing is an SD function. But SAP needs to know, when 
processing a customer's payment, to which GL account the 
payment has to be processed. For instance payment of a UK 
based material would be placed in a different GL account to 
that of a non-UK based material. Furthermore, a UK based 
customer may have a different GL account to that of an 
Export customer. This is configured in Account 
Determination. 

ABAPers are there to essential do some bespoke development. 
Your integration, or interaction, with them would be when 
specifying the tables, fields, input fields, a simple 
process explanation, data mapping (if doing an interface 
from one system to another) etc.  

link between SD and FI :- 

1. Whenever you create a delivery with reference to a sales 
order, goods movement takes place in the bacgground. eg. In 
case of standard sales order, you create an outbound goods 
delivery to the customer. 
Here movement 601 takes place. This movement is configured 
in MM. Also, this movement hits some G/L account in FI. 
Every such movement of good s hits some G/L account. 

2. The accounts posting in FI is done with reference to the 
billing documents (invoice, debit note, credit note etc) 
created in SD. Thus this is a link between SD and FI 

3. Tax determination: In case of a tax determination also, 
there is a direct link between SD and MM 

For SAP FI-MM T.Code OBYC is used to map.
